Can't find this in CSS

Hi there,

When I look at the source code for my website on google chrome I can find the part that needs to be deleted but I can’t find it in my CSS to delete. Can you please help.

</div>
        <div class="social-icon">

            <ul class="social-share-buttons" >
                <li>
                    <a class="twitter" href="https://twitter.com/share?url=http://weddingtest.newlandsbaptist.org.nz/" title="Tweet" target="_blank">
                        <i class="fa fa-twitter"></i>
                        <label class="hidden-xs">Tweet</label>
                    </a>
                </li>
                <li>
                    <a class="facebook" href="http://www.facebook.com/sharer.php?u= http://weddingtest.newlandsbaptist.org.nz/" title="Share" target="_blank">
                        <i class="fa fa-facebook-square"></i>
                        <label class="hidden-xs">Share</label>
                    </a>
                </li>
                <li>
                    <a class="google-plus" href="//plus.google.com/share?url=http://weddingtest.newlandsbaptist.org.nz/" title="+1" target="_blank">
                        <i class="fa fa-google-plus"></i>
                        <label class="hidden-xs">+1</label>
                    </a>
                </li>
                <li>
                    <a class="pinterest"  href="//pinterest.com/pin/create/button/?url=http://weddingtest.newlandsbaptist.org.nz/" title="Pin It" target="_blank">
                        <i class="fa fa-pinterest"></i>
                        <label class="hidden-xs">Pin It</label>
                    </a>
                </li>
            </ul>
        </div>

Thanks
